Abstentions with respect to this proposal will have the effect of a vote against this proposal. Any “broker non-votes,” which occur when brokers are prohibited from exercising voting authority for beneficial owners who have not provided voting instructions or otherwise do not vote on the proposal will be disregarded and have no effect on the outcome of the vote.

(2) Audit-related fees include fees billed for assurance and related services that are reasonably related to the performance of the audit or review of the Company’s consolidated financial statements and are not reported under “Audit Fees.” These services may include employee benefit plan audits, accounting consultations in connection with acquisitions and divestitures, attest services that are not required by statute or regulation, and consultations concerning financial accounting and reporting standards. (3) All other fees include permitted advisory services. The Audit Committee, after consideration of these matters, does not believe that the rendering of these services by CliftonLarsonAllen LLP is incompatible with maintaining their independence as our principal accountants.

Audit Committee Pre-Approval Policy Among other things, the Audit Committee is responsible for appointing, setting compensation for and overseeing the work of the independent registered public accounting firm. We have adopted a pre-approval policy under which the Audit Committee approves in advance all audit and non-audit services to be performed by our independent registered public accounting firm. As part of its pre-approval policy, the Audit Committee considers whether the provision of any proposed non-audit services is consistent with the Security and Exchange Commission’s rules on auditor independence. In accordance with the pre-approval policy, the Audit Committee has pre-approved certain specified audit and non-audit services to be provided by CliftonLarsonAllen LLP for up to twelve months from the date of the pre-approval. All of the services referred to above for 2018 were pre-approved by the Audit Committee.
